simple or complicated solution ?

[DrHuang.com]

wolfram alpha cannot solve some problems in http://12000.org/my_notes/kamek/kamke_differential_equations.htm which are mark as solved in mathematica but its solution are very complicated so it cannot check if it is right answer or not. e. g. problems ode No 64-73, 84.

mathHandbook.com can give simple solution so it is easy to check the answer. it can solve some problems that Mathematica cannot. just copy Maple input to mathHandbook.com, then hit the ENTER key in your keyboard.
